RECORDER.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed July l5, 1913. Serial No. 779,108.

To all whom it may concern:

Be it known that I, EMIL SCHUCH, a subject of the King of Bavaria, residing at 25 Giselastrasse, Munich, Bavaria, Germany, have invented certain new and useful Im` provements in Recorders; and I do hereby declare the following to be a full, clear, and exact description of the invention.

The object of the invention is to provide a new and improved recorder more especially designed for use in connection with lifting machines, block presses, bending presses, forging machines and the like, and arranged to furnish a permanent record of the quality and quantity of the Work and the work done by the machine and the Workmen, at the same time enabling the workmen to accurately apply the pressure of the machine for a predetermined period of time.

In order to accomplish the desired result use is made of an actuating device connected with and controlled by the power medium of the machine, a driven indicator card, a stylus controlled by the said actuating device and marking on the said indicator card, and a second time-controlled stylus in contact with said indicator card for recording time thereon. Use is further made of a driven second hand, means for driving the said second 80 (hand, and a locking and releasing device controlled by the before mentioned actuating device and connected with the said second hand to lock or release the same.

A practical embodiment of the invention is represented in the'accompanying drawing forming a part of this specification, in Which- The Figure 1 is a side elevation of the recorder, parts being Shown in section, Figs. 2 and 3 show details of the locking and releasing device for the second hand in a section on lines A B.

The recorder, hereinafter more fully described in detail, is more especially intended for use on hydraulic and .pneumatic presses and similar machines irrespective of whether the press or machine is driven by hydraulic or pneumatic power, by steam 0r by mechanical means. The recorder has a double function: (1)' to provide a control during the working, and- (2) to form a permanent record after the working. A principal factor during the use of a press or machine is the time in which the machine exerts a pressure on the material to be worked. This time is theoretically and practically fixed and the workman in charge of the machine is made acquainted with the time, but as the workman is not using a stop Watch or similar means it is next to impossible for the workman to maintain the correct time especially as the workmans attention is required in manipulating the machine for .performing certain work, and usually the time taken by the workman for doing the work is too short. The recorder is provided with a polnter indicating on a seconds dial and is normally locked against movement, but is unlocked the moment the full pressure of the machine is exerted on the material to be pressed. By this arrangement the workman is in a position to control the time as a glance at the now movin second hand'indicates the correct time which the pressure is exerted, and consequently the workman can stop the pressure sooner o r later as required by the nature of the material to be pressed. As before stated, a permanent record of the amount of work is obtained and the workin of the machine together with the work o the workman, so that the desired calculations can be accurately made and the parts disposed, as the Work of the machine and that of the workman can be readily determined. On a continually moving indicator card or paper strip are produced two diagrams, of which one represents the hours during which the workman manipulated the machine, and the second diagram indicates in proper sequence the single manipulations of the machine, and this second diagram represents successive phases of each pressing action of crease of the pressure, the maximum pressure and the decrease of the pressure; (2) the time in seconds of each of the three steps mentioned; and (3) the time ofthe day at which the action of the machine took place. The result of the two diagrams is (l) the quantity and quality of the work performed, (2) the Work of the machine (3) the work ofthe workman, and (4) a permanent record for calculation and relative to the machine or the Work done by the Workman. From the four points mentioned, it will be seen that the use of the apparatus is very .important in the fabrication of various articles, and it is expressly understood that the recorder is not for only one particular class of machines but can bei or questions involved.

the machine, namely, (l) the gradual inprincipal devices, namely, a spring motor for moving the indicator card or paper strp forward and for actuating the second han a pressure cylinder controllingl a st lus which indicates the (pressure of t e mac ine; on the indicator car ating a stylus which records the time ofthe day on the indicator card.

A spring motor 1 is connected by a. ear wheel 1 and a pinion 2 with a vertica lydisposed shaft 3 having a gear wheel 4 in mesh with a inion 5 secured on a shaft 5 carrying a ba ance wheel f5 of a timepiece 6* of any approved construction. On the shaft 3 is secured a pinion 7 in mesh with a gear wheel 8 secured on the shaft 9*y of a drum or spool9 for imparting travelin motion from the right to the left to the lndicator card or paper strip 10.: On this strip 10 indicate two styli 2O and 30, of which the stylus 20 is 'actuated by an actuatin device controlled by the power o f the mac ine on which the recorder is used, while the other stylus 30 is driven from a clockwork 26 of any approved construction. The actuating device mentioned is arranged as follows: A cylinder 11, is connected at one end` by a pipe 11* with the source of fluid pressure supply usedl for actuatin the machine on which the recorder is use and in the cylinder 11 is mounted to reciprocate a piston 12 pressed on by a spring 13 bearing against a screw plug 14 screwing into the upper end of the'cylinder lluto permit of regulating the tension of the spring 13. The piston 12 is provided with an annular groove 12l into which projects a pin 15 provided with a rack 16 in mesh with an intermediate gear wheel 17 in mesh with a pinion 18 meshing with a rack 19 carrying at its upper en the stylus 20. Now when pressure is admittedto the machine to actuate the same then the pressure also passes into the lower end ofthe cylinder 11 to force the piston 12 upward therein against the tension of the spring 13. The upward movement of the lpiston 12 causes a likemovement of the pin' 15 and the rack 16 so that a rotary motion-is given to"tha-intermediate gear wheel 17 whereby the pinion 18v is rotated and by` the racks-19 isp-moved upward to.

move the stylus 20'i1'pwa-rd on the indicator card or strip of paperlO. lWhen the presfv sure is cut off from the machine and the cylinder,U 1.1 then -the piston -12. 'isorced dowivns.4

wardback to ormalvposition by the action of thespring 3,A -yvwherebythe` stylus 20 is caused to move downward.

The ,p stylusj 30 is held V on Vthe upper lendf ycfa rogd 29 'provided on its lower end with a friction roller 28 in contact with the pel ripheral face oa heart-shaped cam-27 secured on a shaft 27a forming part of the clockwork 26 and driven by the same. The

clockwork 26 is so arranged that the stylusv and a timepiece actu-.fl

`with a eating on a seconds dial 30 makes its upward sioke during six hours, and in a corresponding number of hours the stylus is caused to travel downward.

On the rack 19 is secured a lug .21 engagin one end of a flat spring 22 fixed at the vot er end on a suitable support. The sprin 22 engages an annular groove of the hub o a bevel ar wheel 24 normally out of mesh vel gear wheel 23 secured on the shaft 3 previously mentioned. On the bevel gear wheel 24 is secured a pointer 25 indi- The operation is as-follows: When the workman opens the' admission valve for admitting the motive agent to the machine then -thel motive agent also passes into the lower end of the cylinder 1l and ushes the piston 12 upward in the cylin er 11.

The upward movement of the piston 12 Y causes the stylus 20 to rise so that the stylusV marks a nearly7 vertical line on the forwardly-moving indicator card or paper strip 10, and after the piston in the machine reaches the resistance of the material to be pressed then the stylus 20 marks a longituinally-'extending line on the indicator card or paper strip 10, and which line is in the form of a large or small segment which finally terminates in a horizontal line, all

according to the amount of resistance encountered in the machine. From this time on the full pressure of the motive agent is exerted by the machine on the material to be pressed and at this time the lug 21 releases the vfree end of the spring 22 so that the gear wheel 24 moves into mesh with the rotating gear 23 whereby the pointer 25 begins to turn. From the foregoing it will4 be seen that the time for maintaining the pressure of the material is indicated by the advancin pointer 25, and when the prescribed tlme has elapsed theoperator closes the admission valve for the' motive agent so that the latter is shut off both from the machine and from the cylinder 11. The piston 12 now moves downward by the action of the spring 13 as previously described and the stylus 2Qjdescends and-"marks a..

nearly'vertcaliirfe. nthefiii'dicator cardV or paper strip `10'."'Du"`ring the downward the lug l21a'ctsI on the' spring 22 soH asto move the bevel ear wheel 24 out of mesh with the gear w eel 23l so that the pointer A25` returnstoits Aze-.rrrlposition bythe action v v of its spring. From the foregoing itwill be seen that each pressing action of the ma-,

`chineis marked on the indicator card 10 v'runpif'ss'o that the indicator card remains Amovement ofthe Stylus and the rack 1 9 "v' stationary and the stylus'30 marks a vertical line thereon. At the beginning of the next working period the indicator card 10 is again caused to travel so that the stylus 30 again marks an inclined upwardly or downwardly-extending line on the indicator card. By the arrangement described the period of rest, that is, the one during which the machine is at a standstill, is indicated in hours and subdivisions thereof.
